INFO: Low frame rate of Arecont Vision network cameras
The information applies to:
- LuxRiot 1.x
Symptoms
Under certain circumstances Arecont Vision network cameras may produce low frame rate (FPS).
Resolution
Typical low frame rate issues and workarounds for Arecont Vision network cameras are:
- Arecont Vision network cameras are not designed for concurrent access. So frame rate will slow down dramatically if two or more users are watching video from the same camera at the same time. Beside this Arecont Vision Network Camera Search Wizard in LuxRiot DVR will not find the camera if this camera already transmits video to some user.
- Arecont Vision megapixel camera consumes large traffic while operating, e.g. AV 3130 camera in max quality mode consumes approx. 20Mbps. Certain network equipment have been noticed to create image transmission problems or slow down frame rate. For example, 3Com routers are not recommended. To bypass network transmission problem try to disable “use double packets” (Advanced tab). This feature specifies whether to use data packets with 2KB instead of the regular 1KB for image transmission (by default, 2KB). This allows increasing image transmission bandwidth, but may lead to a less stable performance on overloaded networks.
